Sixty subjects were included in this study. They were divided in two groups’ viz. group –I (control, without Stevia extract) and group-II (test, gel containing Stevia extract) and each groups contains thirty subjects. They were advised to apply once daily for a period of 21 days. All the subjects were followed up at weekly intervals for a period of 3 weeks. Response to moisturiser gel was evaluated on a scoring system and visual analogue scale. All the subjects were completed the study and significant results observed with respect to reduction in dark complexion, increased in skin softness, skin glow.

The gel is completely free from any reaction due to sun light. None of the volunteers experienced neither any hypersensitivity reactions nor in changes of skin pH and compliance to the use of formulation was potent.
